You might have noticed guest user account on Mac’s login screen. This is not an actual user account, but there is a safety precaution in case you lose your Mac. If you log into default Guest user account, you can notice that Mac will restart to secured version of Safari only. Guest user account will have access to internet. In case when you lose your mac, then if any body finds it then they can go online through this guest user account.
It is good to keep this default guest account on your Mac. Using this guest account no one can access your files, folders and applications. I recommend you to keep this guest user account, but if you want to delete it then here is how to do that.
